Definitions

  • Adsorbent especially moving bed reactor
  • the invention relates to an adsorbent, in particular moving bed reactor, through which the fluid to be treated flows in cross-flow and has at least one essentially vertical, fluid-permeable boundary wall. Furthermore, the invention relates to a fluid-permeable wall component which is particularly suitable as a boundary wall in an adsorbent reactor.
  • Adsorbent reactors with a continuous or quasi-continuously moving bed made of a granular adsorbent are being used to an increasing extent for exhaust gas purification. Certain fluid flow lengths and thus certain reactor cross sections are required for exhaust gas purification. If the exhaust gas to be cleaned contains highly toxic pollutants, such as dioxins, furans or heavy metals, these are already separated by adsorption in a relatively thin vertical layer on the inlet side of the moving bed column. In conventional motors without Reak ⁇ vertical dividing the total amount of the adsorbent to the effluent in the reactor must be treated as special waste, for example, at 1200 C and a ⁇ Ver ⁇ be permanently burned because of at least two seconds. This disposal is extremely expensive.
  • highly toxic pollutants such as dioxins, furans or heavy metals
  • a moving bed reactor in which, in addition to the inlet and outlet side guide plate blinds, a second row of relief plates is installed in the reactor, which are arranged essentially parallel to the inside of the guide plates.
  • the relief plates absorb part of the static side pressure of the downward flowing adsorbent and cause the adsorbent between two guide plates to be relieved of side pressure and to combine with the main stream of the adsorbent in the middle of the moving bed.
  • a moving bed reactor of the generic type in which two adsorbent layers are formed in the reactor bed and are gas-permeable Walls are separated.
  • the known gas-permeable walls are either perforated plates or in the form of blind structures that are inclined in opposite directions. They serve to vary the flow rate of the fluid and are intended to be a compromise solution between loading the entire adsorbent as far as possible on the one hand and adequate cleaning of the exhaust gas on the other hand. Reliable separation into strongly toxic and lightly loaded adsorbent layers is neither provided nor readily possible in this known embodiment.
  • the object of the invention is to achieve the conditions for a simple, precisely definable separation between two vertical layers with reliable prevention of particle crossover and without noticeable impairment of the fluid flows.
  • this object is achieved in that the fluid-permeable wall is designed on the upstream side as a slotted screen with gap limiting elements running from top to bottom, the width of the gap being matched to the grain size of the bulk material so that the solid particles except for fine-grained particles in the upstream part of the Treatment room 38
  • the slotted screen is connected to a stabilizing grid which has connecting elements running transversely to the slit limiting elements; and that a Venetian blind construction with transverse slats is arranged on the downstream side of the stabilizing grille.
  • Adsorptions ⁇ can flow essentially in one plane from top to bottom. Particles of normal size are retained on the upstream side by the boundary wall. The fluid flow, on the other hand, is let through practically unhindered over the entire height of the boundary wall.
  • the intersecting arrangement of the gap limiting elements, the stabilizing grid and the lamellae ensures extremely high dimensional stability, stiffness and stability, so that the properties and the shape of the boundary wall do not change even when the loads are on both sides of the boundary wall fluctuate greatly (for example, through selective loading or removal of the adsorbent on both sides of a partition wall).
  • a further increase in the stability of the boundary wall can be achieved in a further development of the invention in that the stabilizing grid on the outflow side has a plurality of band profiles which cross the connecting elements, the flat sides of the band profiles from top to bottom and essentially parallel to the direction of fluid flow run.
  • a fluid-permeable wall component which is suitable both as a boundary wall on the reactor outlet side and as a partition wall between two chambers of the reactor, is distinguished according to the invention in that the wall component has a sandwich-like construction and is constructed from
  • a slotted screen with essentially parallel slit limiting elements a stabilizing grating which contains connecting elements which run transversely to the slit limiting elements and these intersecting and spaced-apart strip profiles, the flat sides of the strip profiles running essentially parallel and in the direction of layering, and a blind construction with to the gap limiting elements transverse slats.
  • the Venetian blind slats preferably have different directions of inclination.
  • the blind slats In association with a reactor outlet wall, the blind slats have the primary task of collecting fine-grain particles that have passed through the gap-limiting elements and, if possible, discharging them directly into a discharge device.
  • the lamellae, starting from the belt profiles are inclined upwards, preferably at an angle of approximately 25 to 35 "to the vertical plane.
  • the slats of the blind construction have a downward slope.
  • An angle of inclination of 15 to 25 ", in particular approx. 20 ° to the vertical, has proven to be advantageous, since at this angle of inclination the advantages are a reliable rejection of the particle flow on the outlet side of the partition wall and a relatively small wall thickness and compact Construction are combined.
  • the wall component according to the invention creates the prerequisite for the adsorbent flows into the two vertical chambers on both sides of the wall to have different speeds.
  • the vertical layer on the inlet side to be disposed of as special waste can be largely loaded before it is discharged.
  • the subsequent, at least one further vertical layer in the main body of the adsorbent bed can then be discharged continuously or in batches after a completely different cycle.
  • This layer which is largely free of highly toxic trace elements, can be disposed of with relatively simple means, reprocessed or correspondingly inexpensively incinerated in normal incineration plants.
  • the thickness and the cross-section of the individual chambers and thus the position of the partition walls can be selected in accordance with certain ingredients or pollutants in the fluid and with regard to a desired separation behavior.
  • several partition walls can be installed in the reactor such that the cross-flowing fluid flows through at least two partition walls and three chambers in succession.
  • different Fill goods eg more or less highly effective adsorbents
  • the invention can therefore be used regardless of the cross-flow medium used and the adsorbent flows, in principle with the same advantages.
  • the distance from the at least one partition wall to the fluid outlet wall is preferably several times greater than that to the fluid inlet wall. This has the advantage that the inlet-side vertical chamber has relatively small dimensions and the layer volume can be minimized to the size sufficient for the adsorption of the volatile highly toxic substances.
  • the wall component according to the invention can be used in an adsorbent reactor both as a boundary wall on the fluid outlet side of the reactor and as at least one partition wall with the advantages described.
  • the outlet-side boundary wall can also be used in a non-subdivided reactor and - conversely - one or more subdivision walls of the type according to the invention can or can be used in conjunction with an otherwise conventional reactor.

  • FIG. 2 shows a horizontal section through part of a wall component according to the invention, ie a partition wall or part of the reactor outlet wall according to FIG. 1 with a slatted floor consisting of a slotted sieve, a stabilizing grid and a shutter construction (section II -II in Fig. 1);

Abstract

Un réacteur à lit fluidisé forme un adsorbeur à courant transversal. Son lit (3) est subdivisé par au moins une paroi verticale perméable au fluide. Du côté d'afflux, cette cloison forme un crible à fentes (13) avec des éléments (13a) de délimitation des fentes qui s'étendent de haut en bas. Le crible à fentes est relié à une grille de stabilisation (14) ayant des barres de liaison (15) transversales aux éléments de délimitation des fentes et des rubans profilés (16) qui croisent les barres de liaison (15). Du côté de sortie de l'écoulement sont agencées des lamelles (20) inclinées vers le bas faisant partie d'une structure en persienne. La subdidivion verticale par la cloison n'empêche pas le fluide de s'écouler régulièrement à travers le corps du lit mais assure une subdivision fiable du lit du réacteur en deux couches verticales qui peuvent être vidées et nettoyées indépendamment l'une de l'autre. Un agencement similaire du fond à fentes du réacteur sert également de paroi de sortie du réacteur, dont les lamelles de sortie (10), contrairement aux lamelles (20) fortement inclinées vers le bas du côté de sortie de l'écoulement de la cloison, sont fortement inclinées vers le haut du côté de sortie du fluide.
